Bellows and Dressierbälge

Bellows are elastic, hose-like protective covers made of different materials that adapt to defined movement sequences. Through the use of high-tech textiles, combined with selected coatings, they find a wide range of applications. On the one hand, they protect machine parts from external influences (in particular dirt such as dust, oils and fats) and, on the other hand, protect the environment (eg from heat, liquids, flying sparks, dust). RBS bellows are always made by hand exactly to your specifications.

Bellows of the type of manufacture:

Annulus bellows: is sewn together from individual, punched or cut circular rings. The ends are cylindrically shaped so that attachment by means of hose binders is possible. A divisible design is not possible with a circular bellows.

Dressier bellows: A cylinder is formed by the installation of wire rings (if necessary also tension springs or pull-out locks) to a bellows. Through the use of divisible wire rings, a skin pass can be easily mounted around the machine part and closed by zipper, Velcro or snaps.

Other kinds: A stretch bellows is made in one piece (not divisible) and equipped with circular steel rings (similar to a tempering bellows). By taking advantage of the diagonal stretching capability of the fabric gives a good axial range of motion. Again, an attachment by means of hose binders is possible. Furthermore, it is also possible to manufacture cylinders (sprues) reinforced with a sealing ring in various diameters and overall lengths, simple covers and (heat protection) curtains, etc.

Depending on the type of bellows, there are the following possible versions:

Divisible by zipper, velcro or press studs (only for dressage bellows)
With / without flange or flange preparations
Perforations and holes according to customer specifications
Round, angular or combined to form

Bellows construction

Which is the right fabric for a bellows, depends on the given conditions of use and requirements.

Especially the temperature and the medium are in the material selection:

Tarpaulin: suitable for temperatures up to 70 ° C, is often used as dust protection
Glass fabrics - the "all-rounder" among our fabrics: either with double-sided PU or silicone coating is suitable for a temperature range of 250 - 550 ° C.
Aramid fabric with aluminum coating: suitable for temperatures up to approx. 350 ° C, has a high tensile strength
Silicate fabric with aluminum coating or vermiculite coating: for temperatures up to about 1000 ° C, is often used in steelworks and foundries due to the temperature resistance

Bellows are mainly used as cover and protection for cardan shafts, piston rods, cylinders, etc. in various industries. Among other things, they protect against all types of contamination (dust, metal and wood chips, etc.), liquids, heat, oils and fats, flying sparks, etc.

Our bellows are specially designed for the high temperature range and can be used at temperatures up to 1000 ° C. A suitable fabric construction also allows use under aggressive conditions (eg by flue gases).
